Question

The sequence -10, -6, -2, 2, . . .
(A) is an A.P., Reason d = -16 (B) is an A.P., Reason d = 4
(C) is an A.P., Reason d = -4 (D) is not an A.P

Answer 1

Step-by-step explanation:

d=a2-a1=a3-a2=a4-a3

a1=-10,a2=-6,a3=-2, a4=2

Therefore,

a2-a1=a3-a2=a4-a3

-6-(-10)=-2-(-6)=2-(-2)

-6+10=-2+6=2+2

4=4=4

Hence, (B) is correct option
